超级稻连粳7号不同播(栽)期与株行距配置对产量结构的影响

摘要

The effect of different sowing date and plant and row spacing on yield structure of super rice named Lianjing-7 was analysed that early sowing and early transplanting can increase yield under the same level of plant and row spacing, the late sowing and transplanting can decrease yield, the early transplanting can widen row-spacing and late sowing and transplanting can narrow row-spacing to assure the yield.%通过对超级稻连粳7号不同播(栽)期与株行距配置对产量结构的影响试验比较分析,初步认为对于同一株行距,及时早播(栽),产量表现就越好,播(栽)越晚,产量表现就差;对于不同株行距,适期早播(栽)的,行距可以适当放宽,随着播(栽)期的推迟,行距应作相应的缩减,有利于产量水平的提高.
